Confirmatory factor analyses with a calibration and a cross-validation sample (total N 930) showed that four recovery experiences can be differentiated: psychological detachment from work, relaxation, mastery, and control (Study 2). Examination of the nomological net in a subsample of Study 2 (N 271) revealed moderate relations of the recovery experiences with measures of job stressors and psychological well-being; relations with coping and personality variables were generally low (Study 3). Potential applications for the future use of these short 4-item measures in longitudinal and diary research are discussed. Keywords: job stress, recovery, unwinding, scale development Individuals who face stressful work situations experience poor psychological well-being and tend to suffer from health problems (De Lange, Taris, Kompier, Houtman, & Bongers, 2003; Sonnentag & Frese, 2003). For example, individuals exposed to job stressors have an increased likelihood for developing burnout and other symptoms of poor wellbeing (Demerouti, Bakker, & Bulters, 2004; Garst, Frese, & Molenaar, 2000). In addition, stressful work situations might negatively affect job performance (Jex, 1998). Processes related to recovering and unwinding from job stressors can be relevant for individuals health, well-being, and job performance (decroon, Sluiter, & Blonk, 2004; Eden, 2001). However, past research on recovery and recuperation from job stress mainly focused on general effects of off-job episodes such as vacations (Fritz & Sonnentag, 2006; Sabine Sonnentag, Department of Psychology, University of Konstanz; Charlotte Fritz, Department of Psychology, Bowling Green State University.

Because the underlying psychological experiences associated with recovery gained little research attention so far (for an exception see Fritz & Sonnentag, 2005), it remains unexplored why specific off-job activities are associated with recovery. Probably, it is not a specific activity per se that helps to recover from job stress but its underlying attributes such as relaxation or psychological distance from job-related issues. Persons may differ with respect to the specific activities they experience as recovering while the underlying psychological experiences crucial for recovery may be relatively uniform across persons. For example, one person might recover from job stress by going for a walk while the other recovers by reading a book. Although the activities are different, the underlying processes (e.g., relaxation) are rather similar. Going beyond the specific activities and examining the underlying experiences is crucial for getting more insight into the psychological processes leading to recovery. To this end, it is necessary to have reliable and valid measures available that capture the core functional aspects of such recovery experiences. In this paper, we present a new instrument that assesses specific recovery experiences, namely psychological detachment from work, relaxation, mastery, and control. In addition, we examine the relation between these recovery experiences and potential predictors (work situation 204

2 RECOVERY EXPERIENCE QUESTIONNAIRE 205 variables, coping, and personality) as well as potential consequences (psychological well-being). Conceptualizations of Recovery Recovery refers to a process during which individual functional systems that have been called upon during a stressful experience return to their prestressor levels (Meijman & Mulder, 1998). The recovery process can be seen as a process opposite to the strain process. It results in restoration of impaired mood and action prerequisites and is often also reflected in a decrease in physiological strain indicators. To develop an understanding of successful recovery experiences we draw on theories on recovery processes (Effort-Recovery Model; Conservation of Resources Theory) as well as on the mood regulation literature. The Effort-Recovery Model (Meijman & Mulder, 1998) holds that effort expenditure at work leads to load reactions such as fatigue or physiological activation. Under normal conditions, once the individual is no longer exposed to the work or similar demands, load reactions are reversed and recovery occurs. According to this model, it is an important precondition for recovery that the functional systems taxed during work will not be called upon any longer. The Conservation of Resources Theory (Hobfoll, 1998) assumes that people strive to obtain, retain, and protect their resources. Resources can be external entities such as objects or financial assets as well as internal attributes such as personal characteristics or energies. Stress threatens these resources and as a consequence may harm health and well-being. To recover from stress, individuals have to gain new resources and restore threatened or lost resources. Stress recovery on a day-to-day basis particularly refers to internal resources such as energy or positive mood. Thus, the Effort-Recovery Model and the Conservation of Resources Theory suggest two complementary processes by which recovery occurs. First, it is important to refrain from work demands and to avoid activities that call upon the same functional systems or internal resources as those required at work. Second, gaining new internal resources such as energy, self-efficacy or positive mood will additionally help to restore threatened resources. Research on mood regulation offers a more specific insight into the processes that are relevant for recovery. Because stressful work conditions often lead to impaired mood (Fuller et al., 2003), mood repair is one of the core functions of recovery. Research on mood regulation identified a range of different strategies individuals pursue to improve their mood including both cognitive and behavioral approaches (Parkinson, Totterdell, Briner, & Reynolds, 1996; Thayer, Newman, & McClain, 1994). Parkinson and Totterdell (1999) suggested a classification of mood regulation strategies comprising diversionary strategies and engagement strategies. Diversionary strategies aim at avoiding a negative or stressful situation and at seeking distraction from it. Engagement strategies are characterized by confronting or accepting the negative or stressful situation. Diversionary strategies seem to be most relevant and promising for stress recovery because engagement strategies keep the individual cognitively occupied with the stressful situation and its potential effects which make recovery less likely. Recovery Experiences Among others, diversionary strategies comprise psychological detachment from work (i.e., mentally switching off), relaxation-oriented strategies, and mastery-oriented strategies (Parkinson & Totterdell, 1999). These divisionary strategies, particularly detachment from work and relaxation-oriented strategies, should be useful for recovery because they imply that no further demands are made on functional systems called upon during work. Mastery-oriented strategies should support the recovery process by building up new internal resources (e.g., selfefficacy). In addition, because control is a crucial external resource that provides the opportunity to gain internal resources (Hobfoll, 1998), we propose that the experience of control is one important recovery experience. Psychological Detachment Although being physically away from the workplace might be important for recovery, it may not be sufficient (Hartig, Johansson, & Kylin, 2007). We propose that becoming psychologically detached from work is a crucial aspect of any recovery process. Etzion, Eden, and Lapidot (1998) introduced the term detachment to describe an individual s sense of being away from the work situation (p. 579). Detachment implies not to be occupied by work-related duties such as receiving job-related phone calls at home or actively engaging in job-related activities. In our view, psychological detachment also means to disengage oneself mentally from work. It implies to stop thinking about one s work and job-related problems or opportunities. Psychological detachment from work goes beyond the pure physical absence

3 206 SONNENTAG AND FRITZ from the workplace during off-job time and abstaining from job-related tasks. It implies leaving the workplace behind oneself in psychological terms (Sonnentag & Bayer, 2005). According to the Effort-Recovery Model, recovery occurs when no further demands are made on the functional systems called upon during work (Meijman & Mulder, 1998). When individuals psychologically detach from work during off-job time, the chances increase that demands on the functional systems taxed during work are reduced. However, when individuals do not detach and are still thinking about job-related issues, the identical functional systems are continuously challenged and no full recovery can occur. Empirical evidence suggests that psychological detachment is related to recovery from job stress. For example, Etzion et al. (1998) showed that detachment exerts a moderating effect on the relation between stressors and burnout. Using daily survey data, Sonnentag and Bayer (2005) reported that individuals experiencing psychological detachment from work during leisure time reported better mood at the end of the evening. Relaxation Relaxation is a process often associated with leisure activities. It is characterized by a state of low activation and increased positive affect (Stone, Kennedy-Moore, & Neale, 1995). Relaxation may result from deliberately chosen activities aiming at the relaxation of body and mind such as progressive muscle relaxation (Jacobson, 1938) or meditation (Grossman, Niemann, Schmidt, & Walach, 2004). Some degree of relaxation may also be achieved when performing other activities such as taking a light walk in a beautiful natural environment (Hartig, Evans, Jamner, Davis, & Gärling, 2003) or listening to music (Pelletier, 2004). Many individuals expect relaxation from activities that put few social demands on them, that require little physical or intellectual effort, and that present no challenge to them (Tinsley & Eldredge, 1995). The potential for relaxation experiences to reduce activation and to increase positive affect are important for recovery in two respects. First, as Brosschot, Pieper, and Thayer (2005) suggested, prolonged activation resulting particularly from stressful work is an important mediating mechanism by which job stressors translate into illness. Therefore, processes that reduce this prolonged activation are crucial in order to restore an organism s prestressor state. Second, Frederickson (2000) argued that positive emotions can undo the effects of negative emotions. Positive affect resulting from relaxation experiences will be helpful in reducing negative affect resulting from job stress. Empirical evidence suggests that relaxation experiences help in reducing stress-related complaints, in the short as well as in the long run (Stone et al., 1995; Van der Klink, Blonk, Schene, & Van Dijk, 2001). Mastery Experiences Mastery experiences refer to off-job activities that distract from the job by providing challenging experiences and learning opportunities in other domains. These activities offer opportunities for experiencing competence and proficiency. Typical examples include taking a language class, climbing a mountain, or learning a new hobby (Fritz & Sonnentag, 2006). Also volunteer work in which one can demonstrate one s competencies can include aspects of mastery experiences (Ruderman, Ohlott, Panzer, & King, 2002). Mastery experiences challenge the individual without overtaxing his or her capabilities. Attaining mastery experiences is not necessarily effortless but requires a certain degree of self-regulation. For example, for experiencing mastery by taking a language class, it is necessary to exercise some control over oneself in order to drive to the course and to overcome the impulse to spend a lazy evening at home (cf. Vohs & Baumeister, 2004). Although mastery experiences might put additional demands on the individual, these experiences are expected to result in recovery because they will help to build up new internal resources such as skills, competencies, and self-efficacy (Bandura, 1997; Hobfoll, 1998). In addition, mastery experiences during off-job time will help in improving positive mood (Parkinson & Totterdell, 1999). First empirical evidence suggests that mastery experiences during off-job time are related to recovery. For example, mastery experienced during a vacation was negatively related to exhaustion after the vacation (Fritz & Sonnentag, 2006). Similarly, the pursuit of sport an activity that is often associated with mastery experiences is related to an improvement in affect (Rook & Zijlstra, 2006; Sonnentag & Natter, 2004). Control During Leisure Time Individuals have a general desire to control events in their life (Kelley, 1971). Control can be described

4 RECOVERY EXPERIENCE QUESTIONNAIRE 207 as a person s ability to choose an action from two or more options. Here, we will focus on the degree to which a person can decide which activity to pursue during leisure time, as well as when and how to pursue this activity. Personal control seems to be associated with positive reactions (Burger, 1989). It can lead to a positive reevaluation of potentially stressful situations and is associated with lower distress and higher psychological well-being (Lazarus, 1966). Using an experience-sampling approach, Larson (1989) found that the experience of control during the day was positively related to happiness. Thus, individual wellbeing is increased when one feels in control of important life domains (Bandura, 1997). In contrast, the perception that one s ability to react to and influence the social world is reduced can be associated with higher levels of psychological distress (Rosenfield, 1989). This experience of low control can further result in negative self-evaluations and decreased self-worth which again can be associated with anxiety or depression (Rosenfield, 1989). The experience of control during leisure time may satisfy one s desire for control by increasing selfefficacy and feelings of competence, which in turn promote well-being. In this sense, control may act as an external resource that enhances recovery from work during off-job time. In addition, control during leisure time gives the individual the opportunity to choose those specific leisure activities that he or she prefers and that may be especially supportive for the recovery process. Increased levels of recovery may then become evident in a person s increased wellbeing and potential for action regulation. Accordingly, Griffin, Fuhrer, Stansfeld, and Marmot (2002) found that women experiencing low control at home showed higher levels of depression five years later than women high in control at home while men experiencing low control at home showed higher levels of depression as well as anxiety than men with high control at home. Potential Predictors and Consequences of Recovery Experiences Job Stressors and Job Control as Potential Predictors of Recovery Experiences We propose that job stressors and job control are associated with recovery experiences. Job stressors are conditions in the work situation that make action regulation more difficult (Frese & Zapf, 1994). Typical job stressors include workload (time pressure, overtime), role ambiguity, and situational constraints. Job control refers to an individual s discretion to determine the timing and methods of his or her actions (Jackson, Wall, Martin, & Davids, 1993) and is seen as a resource in the action regulation process (Frese & Zapf, 1994). We expect negative relations of job stressors with all four recovery experiences. First, individuals facing job stressors such as time pressure or overtime might find it difficult to detach from work during off-job time. When experiencing job stressors, that is when being confronted with problems and time constraints at work, individuals will be more likely to keep thinking about their job in order to develop solutions for these difficulties. In addition, they will anticipate problems and constraints for the next working day. Empirical evidence suggests that stressful job situations are negatively related to psychological detachment from work during off-job time (Cropley & Purvis, 2003; Grebner, Semmer, & Elfering, 2005). Second, job stressors will be negatively related to relaxation experiences off the job. Research has shown that exposure to stressors is associated with prolonged activation (Brosschot et al., 2005). For example, employees exposed to high job stress showed elevated heart rate and systolic blood pressure after work (Vrijkotte, Van Doornen, & De Geus, 2000). This higher level of activation caused by job stressors will make it more difficult to arrive at a state of relaxation during off-job time. Third, job stressors increase fatigue (Zohar, Tzischinski, & Epstein, 2003) which makes it more difficult to engage in self-regulatory processes (Muraven, Tice, & Baumeister, 1998). Because activities that result in mastery experiences require a certain degree of effort and self-regulation, job stressors and associated fatigue will make it less likely to experience mastery off the job because it is more difficult to initiate and uphold the respective activities. Accordingly, research showed that job stressors are negatively related to the engagement in active leisure activities such as sport (van Hooff, Geurts, Kompier, & Taris, 2007). Job stressors may also decrease the experience of control outside work. For example, high work demands in terms of long work hours or work brought home leaves less time available for leisure activities. This reduces the amount of time the individual can have control over during off-work time. In addition, as mentioned above, job stressors such as time pressure or situational constraints may increase fatigue (Zohar et al., 2003). This may reduce the amount of internal resources available for self-regulation and

5 208 SONNENTAG AND FRITZ decision making. As a result, the individual may perceive to have lower control during leisure time although the objective level of control may be unchanged. With respect to job control we expect a less uniform pattern of relations. We hypothesize negative relations between job control and psychological detachment and relaxation, and positive relations with mastery and control. Job control means having decision latitude about how to do one s work. This implies that often several options about how to proceed are available. Therefore, one will be more inclined to continue thinking about one s job after work and psychological detachment from work will be more difficult. Similarly, because high job control will stimulate continuous thinking about work during offjob time, relaxation will be more difficult (Brosschot et al., 2005). Job control enables individuals to take an active approach toward their environment that is reflected in the pursuit of learning activities (Taris & Kompier, 2005) and other proactive behaviors (Frese, Kring, Soose, & Zempel, 1996). Because of spillover processes across different life domains (Edwards & Rothbard, 2000) such an active approach should generalize beyond the job domain and result in the enactment of more mastery experiences also during off-job time. Moreover, job control enables individuals to adapt their working strategies and effort expenditure to their current state (Taris et al., 2006). As a consequence, they will be less fatigued after work and will find it less difficult to engage in effortful activities that provide the opportunities for mastery experiences. Perceiving and experiencing job control will make it more likely that an individual will also try to exert control during off-job time (Meissner, 1971). This means that perceptions of control may spill over into the nonwork domain and that experiencing job control will be associated with high levels of experienced control during off-job time. Coping Styles as Potential Predictors of Recovery Experiences We assume that coping styles are related to recovery experiences. Lazarus and Folkman (1984) defined coping as constantly changing cognitive and behavioral efforts to manage specific external and/or internal demands that are appraised as taxing or exceeding the resources of the person (p. 141). As coping refers to an individual s attempts to deal with stress, recovery activities can be seen as a way of timedelayed coping with job stress. However, the concepts are not identical. Whereas coping refers to the stressor and to the way individuals deal with it, recovery refers to the way they restore their internal resources. One categorization of coping styles refers to the differentiation between problem-focused and emotion-focused coping (Lazarus & Folkman, 1984). Problem-focused coping includes problem-solving behaviors and aims at directly addressing and changing the stressor or other aspects of the situation. Examples of problem-focused coping include active coping, planning, suppression of competing activities, restraint coping, and seeking of instrumental social support (Carver, Scheier, & Weintraub, 1989). Emotion-focused coping refers to attempts to manage cognitions or emotions directly, without changing the environment. Examples include seeking of emotional social support, positive reinterpretation, acceptance, or denial. Carver et al. (1989) suggested a third category including less successful coping attempts such as focus on emotions and disengagement. We propose that some, but not all, coping styles are associated with recovery experiences. Specifically, we do not expect a significant relation between problem-focused coping and psychological detachment from work or relaxation. One might argue that seeking solutions for work-related problems or stressors keeps individuals cognitively busy with the problem so that psychological detachment and relaxation would be impeded. However, as problemsolving attempts probably already during working time are successful individuals will find it easier to detach themselves from work during off-job time and to relax. We expect that problem-focused coping will show positive, albeit weak, relations with mastery and control. Individuals who actively address stressors might also approach their off-job time more actively. Therefore, they will engage more in activities that provide mastery experiences and will experience more control. With respect to emotion-focused coping we propose a positive relation with all four recovery experiences. As individuals try to manage their cognitions and emotions related to job stress, they will try to seek experiences that give them some relief and improve their positive mood. However, particularly with respect to mastery and control we do not expect strong associations. When it comes to the coping styles that Carver et al. (1989) assumed to be less useful such as disengagement or focus on emotions, the similarity between disengagement and psychological detachment from work is obvious.

6 RECOVERY EXPERIENCE QUESTIONNAIRE 209 Therefore, we hypothesize a positive relation between disengagement and psychological detachment. With respect to the other three recovery experiences or focus on emotions, we do not propose any significant relations. Personality as a Potential Predictor of Recovery Experiences We propose that some, but not all, of the Big Five personality dimensions are related to recovery experiences. We mainly postulate relations between conscientiousness and emotional stability on the one hand and recovery experiences on the other. Except for one specific relation we do not expect openness to experience, agreeableness, and extraversion to be related to the recovery experiences. Conscientiousness refers to the extent to which an individual is orderly, self-disciplined, achievementoriented, and reliable (Barrick & Mount, 1991; Costa & McCrae, 1992). As conscientious individuals take their jobs seriously, they might also think about their jobs during off-job time. For example, they might reflect about how to do their work during the upcoming workday. It will be more difficult for them to psychologically detach from work and relax during off-work time. At the same time, because they are achievement-oriented, they might not limit their ambitions and self-discipline to their jobs but will also deliberately pursue activities that offer mastery experiences in other life domains. Emotional stability is an individual s tendency to experience positive emotional states and to show good emotional adjustment to stressful events (Costa & McCrae, 1992). It is necessary for regulating one s feelings and reactions to stress. Therefore, individuals high in emotional stability will not be bothered much by stressful events encountered at work. They will find it easier to psychologically detach themselves from work and relax during off-job time. As emotionally stable individuals have a more positive approach toward their lives, they will also be more inclined to seek challenging experiences during offjob time. As they are more tolerable toward stressful situations, they will be more willing to accept the demanding nature of activities associated with mastery experiences. Therefore, we hypothesize that emotional stability will be positively related to mastery experiences. In addition, we propose a positive relation between emotional stability and control during off-job time. As time off the job is often associated with additional stressors from the family domain, individuals high on emotional stability might feel less emotionally affected by these stressors and experience more control. Openness to experience describes individuals in terms of their creativity, flexibility, and willingness to take risks (Costa & McCrae, 1992). Because individuals high on openness to experience are curious and search for new learning opportunities, we expect that they will look for opportunities to engage in mastery experiences. Therefore, we hypothesize a positive relation between openness to experience and mastery. We do not expect that openness to experience will be related to any of the three other recovery experiences. Agreeableness is an individual s tendency to be kind, gentle, and to get along well with others in social settings (Costa & McCrae, 1992). Therefore, agreeableness should be related to the quality of interpersonal relations during off-job time. However, it should be independent of the four recovery experiences. Extraversion refers to the extent to which individuals are sociable, assertive, and energized by social interactions (Costa & McCrae, 1992). We assume that both extravert and introvert individuals have the potential to psychologically detach from work, to relax, to experience mastery and control although the specific activities by which they reach these experiences may largely differ. Psychological Well-Being as a Potential Consequence As recovery experiences help in unwinding from stress, they will contribute to psychological wellbeing. Here we focus on indicators of (impaired) well-being (e.g., burnout, health complaints, and depressive symptoms), need for recovery, life satisfaction, and sleep. Unfavorable work situations are associated with impaired psychological well-being such as health complaints (Leitner & Resch, 2005), burnout (Maslach, Schaufeli, & Leiter, 2001), or depressive symptoms (Dormann & Zapf, 2002). We propose that recovery experiences are negatively related to these three indicators of impaired psychological well-being. Work causes strain reactions in the individual that will accumulate and in the long term may develop into health complaints, burnout, or depressive symptoms if they are not reversed (Meijman & Mulder, 1998). Recovery experiences have the potential to undo these strain reactions.

7 210 SONNENTAG AND FRITZ Therefore, we hypothesize that the recovery experiences are negatively related to health complaints, burnout, and depressive symptoms. Need for recovery is a specific aspect of impaired well-being and refers to the desire for being temporarily relieved from demands in order to recuperate and to replenish internal resources (Sluiter, Van der Beek, & Frings-Dresen, 1999). Individuals who chronically experience a high need for recovery feel that the time regularly available for recovery is not sufficient for restoring their internal resources. We hypothesize that recovery experiences are negatively related to need for recovery. Life satisfaction is a subjective global judgment of a person s quality of life (Diener, Emmons, & Larson, 1985). Research showed that life satisfaction is not only influenced by top-down processes with personality factors affecting life satisfaction, but also by bottom-up processes with domain-specific satisfactions impacting on life satisfaction (Heller, Watson, & Ilies, 2004). Individuals with favorable recovery experiences will tend to be more satisfied with their leisure time which in turn will be positively related to life satisfaction. Empirical research suggests that recovery-related experiences are related to life satisfaction (Strauss-Blasche, Ekmekcioglu, & Marktl, 2002). Therefore, we hypothesize that recovery experiences are positively related to life satisfaction. Sleep in itself is important for recovery. During sleep, many functions of the organism are restored. In addition, positive recovery experiences should reduce the strain level built up during the working day and should in turn enhance sleep quality. For example, when not sufficiently detaching from work and when keeping thinking about work-related issues, sleep onset and sleep quality will be impaired. Similarly, when relaxation after work is missing, activation will continue which will make it more difficult to fall asleep. Mastery and control will give the individual a feeling of satisfaction and accomplishment that will have a positive impact on sleep quality. Table 1 summarizes the hypothesized relations between recovery experiences and potential predictors and consequences. Study 1: Item Generation and Item Review Our first study aimed at generating and reviewing items to assess recovery experiences. For all four dimensions (i.e., psychological detachment, relaxation, mastery, control), we generated items that should tap the respective construct. For generating these items, we referred to the description of the constructs as outlined in the introduction of this article, reviewed the literature on recovery and on mood regulation, and used brainstorming techniques to cover a broad range of experiences that reflect these constructs. In total, we generated 47 items, 8 items for psychological detachment, 11 items for relaxation, 16 items for mastery, and 12 items for control. To examine content validity of these items we provided 16 advanced psychology students with descriptions of the four dimensions and presented the items to them in a random order. Five students (31.3%) were in their third year of psychology major, two students (12.5%) were in their fourth year of psychology major, five students (31.3%) were in their fifth year of psychology major, and four participants (25%) were even more advanced psychology students. The students were asked to classify each item into one of the four dimensions or to an additional other category. To reduce the workload for each individual rater, eight raters classified a first set of 23 items, eight other raters classified a second set of 24 items. All items that were classified to the correct a priori category by at least 75% of the raters were retained. Based on this decision rule, a total of 35 items remained: 6 items for psychological detachment, 9 items for relaxation, 11 items for mastery, and 9 items for control. Because psychological detachment had only six items remaining, we kept the two original items that did not meet the 75% decision rule. Both items were correctly classified by 62.5% of the raters. Thus, we used 37 items for further scale development. Study 2: Examining Construct Validity Sample and Procedure Because recovery opportunities and recovery experiences may largely vary between jobs, we sampled employees from a variety of different jobs. To recruit study participants, we first contacted managers of a broad range of different organizations in various business sectors. After the managers expressed interest in participation, we approached the employees either by mail or in person at their workplace, presented the study and asked for participation. We contacted a total of 1409 persons by mail and 420 persons directly at their workplace. All these potential participants were provided with the survey material and a cover letter describing the study. Per-

Surveys completed by the persons contacted directly were collected by a member of the research team. From the persons contacted by mail, 755 questionnaires were returned (response rate of 53.6%). From the persons directly contacted, 236 questionnaires were returned (response rate of 56.2%). A total of 991 questionnaires were returned, for an overall response rate of 54.6%. Most participants were women (71%). Participants mean age was 38.3 years (SD 12.3), mean job tenure was 15.1 year (SD 11.2). Among all participants, 24.0% had a supervisory position. Of the total sample, 58.0% had children with an average of 1.8 children. Participants came from a broad variety of private and public organizations with 26.7% working in the public administration, 18.3% as teachers in schools, 11.0% in call centers, 9.6% in hospitals, 9.3% in nursing homes, 6.0% in public relation agencies, 4.5% in retail companies, and 4.1% in insurance organizations. The remaining participants came from a manufacturing company, banks, hotels, travel agencies, and other service organizations. The percentage of participants working irregular hours was 18.6%. Data on psychological detachment from N 148 teachers participating in this study were also used in another study (Sonnentag & Kruel, 2006). Measures The survey included a total of 37 items assessing recovery experiences (psychological detachment: 8 items, relaxation: 9 items, mastery: 11 items; control: 9 items). Participants were asked to respond to the items with respect to their free evenings (e.g., During time after work, I kick back and relax ) on a 5-point scale from1 (I do not agree at al) to5(i fully agree). Moreover, we assessed gender, age, number of children, job tenure and occupation. In a subsample (N 271), we additionally measured a range of other variables to examine the nomological net of the recovery experience measures (see Study 3). Strategy for Analyzing Data To examine the construct validity of our recovery experience measures, we used a cross-validation approach and randomly split the overall sample (N 991) into two subsamples. Because of missing values, sample size in each of the two subsamples was N 465. We used the first subsample for finding the best-fitting model (calibration sample) and then cross-validated this model with the second subsample (cross-validation sample).

9 212 SONNENTAG AND FRITZ Results By using calibration sample data, we submitted a covariance matrix based on the 37 items derived from Study 1 to a set of Confirmatory Factor Analyses. First, we separately fitted single-factor models for each of the four constructs and then fitted two-factor models for all possible pairs of constructs (relaxation vs. mastery, relaxation vs. psychological detachment, relaxation vs. control etc.). Subsequently, we deleted items that (a) had very high cross-loading on another than the intended factor, (b) showed high acrossfactor correlated measurement errors, and (c) low loadings on the intended factor (modification indices exceeding and factor loadings below 0.50). This procedure resulted in a set of 20 items. We conducted a Confirmatory Factor Analysis with these 20 items by specifying a four-factor structure. Analysis showed a reasonable, although not very good fit ( ; df 164; GFI.88; NNFI.96; CFI.95; RMSEA.078; SRMR.055). To arrive at a better model fit and at shorter, more parsimonious scales, we again removed some items based on the above specified criteria. The final model comprised 16 items with an acceptable fit ( ; df 98; GFI.92; NNFI.97; CFI.97; RMSEA.069; SRMR.045). We compared this four-factor model with alternative one-factor, twofactor, and three-factor models. Table 2 shows the fit indices of the best-fitting two-factor models and bestfitting three-factor models. The four-factor model showed a significantly better fit than the one-factor model ( ; df 6; p.001), all two-factor models ( ; df 5; p.001), and all three-factor models ( ; df 3; p.001). In the next step, we further examined this factor structure with the cross-validation sample. We first tested a model with the 20 items used in the calibration sample. This 20-item model resulted in a reasonable but slightly worse fit than analysis with the calibration sample ( ; df 164; GFI.87; NNFI.95; CFI.96; RMSEA.084; SRMR.060). The four-factor model with 16 items resulted in an acceptable fit ( ; df 98; GFI.90; NNFI.96; CFI.96; RMSEA.082; SRMR.049) although the RMSEA slightly deviated from the recommended value of.080. Again, this four-factor model showed a better fit than the one-factor model ( ; df 6; p.001), all two-factor models ( ; df 5; p.001), and all three-factor models ( ; df 3; p.011). Table 3 displays items wordings, factor loadings, and alphas for both subsamples. Taken together, the confirmatory factor analyses showed that the four recovery experience scales represent distinct constructs and show good reliability. Table 4 shows that the correlations among the latent variables were moderate. Only relaxation and control were rather highly correlated. For further analyses we used the unweighted means of all scale items as indicators for the respective scales.

Study 3: Examining the Nomological Net Study 3 aimed at analyzing the nomological net of the four recovery experience measures by examining their relations with potential predictors and consequences. Sample Two subsamples from Study 2 participated in this study. Subsample 1 comprised 134 persons (47% men). Mean age was 40.9 years (SD 10.4); mean job tenure was 18.4 years (SD 11.2). About a third (32.1%) of the first subsample held a supervisory position. Of all participants in this subsample, 53% had children with an average of 2.0 children. Most participants came from local public administration organizations (86.8%). The other participants worked in travel agencies (7.8%) and retail organizations (5.4%). Subsample 2 comprised 137 persons (60.6% men) with a mean age of 38.6 years (SD 9.6) and mean job tenure of 15.3 years (SD 9.4). Of these 137 persons, 30% worked in a supervisory position. About a half (52.6%) of the participants had children with an average of 1.8 children. Participants worked in the field of local public administration (79.9%), in a technical service company (7.5%), travel agencies (7.6%), and retail organizations (6.0%).

Correlations above the diagonal are from the calibration sample. Correlations below the diagonal are from the cross-validation sample. All correlations are significant at p.01. There were no mean differences in the four recovery experience scales, neither between these two subsamples nor between these two subsamples and participants who only participated in Study 2. Overall, also the correlational patterns did not differ between the various subsamples. However, the correlation between relaxation and control in the two subsamples was somewhat higher, r.64, N 271, than in the larger sample (excluding the two subsamples), r.51, N 719, z 2.72, p.01. Measures In both subsamples we assessed job stressors and job control. We additionally measured coping and personality variables in subsample 1, and psychological well-being in subsample 2. We decided not to measure all variables in both subsamples in order not to impose heavy time demands on our participants when completing the surveys. Table 5 displays means, standard deviations, correlations, and alphas for all study variables. Higher scores indicate a higher degree of the phenomenon under study. Work situation variables. We assessed job stressors and job control with measures developed by Semmer (1984; cf. Zapf, 1993). To cover different job stressors, we assessed time pressure, role ambiguity, situational constraints, and hours of overtime. We measured time pressure with five items (e.g., How often is a fast pace of work required of you? ) using a 5-point scale from 1 (almost never) to5(very often). For assessing role ambiguity we used five items (e.g., How often do you receive contradictory instructions from different supervisors? ) with a 5-point scale from 1 (almost never) to5(very often). We measured situational constraints with five items describing two contrasting workplaces (e.g., Person A must spend a lot of time in order to get information and/or materials to pursue his or her work activity. Person B always has the necessary information and/or materials at his or her disposal. ). On a 5-point scale from 1 (my job is exactly like that of Person B) to5(my job is exactly like that of Person A), participants had to indicate which of the descriptions most adequately characterized their work situation. We assessed hours of overtime with one single item. We measured job control with five items (e.g., Can you yourself decide on which way to carry out your work? ) using a 5-point scale from 1 (very little) to5 (to a very large extent). Coping. We assessed coping in subsample 1 with the COPE measures (Carver et al., 1989) in their German version (Vollrath & Torgersen, 2000). We measured four coping strategies representing problem-focused coping (active coping, planning, restraint coping, use of instrumental social support), two coping strategies representing emotion-focused coping (denial, use of emotional social support), and three other coping attempts (focus on emotions, behavioral disengagement, mental disengagement). All coping strategies were assessed with four items each on a 4-point scale from 1 (never) to4(often). Personality. We assessed the Big Five personality factors in subsample 1 with the German Version (Lang, Lüdtke, & Asendorpf, 2001) of the Big Five Inventory (John & Srivastava, 1999) and measured conscientiousness with nine items, emotional stability with seven items, openness to experience with 10 items, extraversion with eight items, and agreeableness with eight items on 5-point scales from1 (not at all) to5(very much). Psychological well-being. In subsample 2 we assessed health complaints, burnout, depressive symptoms, need for recovery, life satisfaction, and sleep problems as indicators of (poor) psychological wellbeing. We measured health complaints with 12 items from the General Health Questionnaire (Goldberg, 1972; e.g., Did you experience a lack of selfconfidence during the last two weeks? ) on a 4-point scale from 1 (not at all) to4(much more than usual). We measured burnout with the Oldenburg Burnout Inventory (Demerouti, Bakker, Nachreiner, & Schaufeli, 2001) and assessed emotional exhaustion (e.g., After my work I usually feel worn out and weary ) and disengagement (e.g., I usually talk about my work in a derogatory way ) with eight items each on a 4-point scale from1 (fully disagree) to4(fully agree). We assessed depressive symptoms with eight items developed by Mohr (1986; e.g., I am often in a sad mood ). We used a 7-point re-

12 RECOVERY EXPERIENCE QUESTIONNAIRE 215 sponse scale from 1 (almost always) to 7(never) that was reversed for correlational analysis. Need for recovery was measured with 11 items (van Veldhoven & Broersen, 2003; e.g., At the end of a working day I am really feeling worn-out ) using a 4-point scale from 1 (never) to 4 (always). For measuring life satisfaction we used five items from the Satisfaction With Life Scale (Diener et al., 1985; e.g., In most ways my life is close to my ideals ) to be answered on a 7-point scale from 1 (fully disagree) to 7(fully agree). We measured sleep problems with nine items from the Pittsburgh Sleep Quality Index (Buysse, Reynolds, Monk, Berman, & Kupfer, 1989) using a 4-point scale from 1 (not at all) to4(three times or more per week). Results Table 5 shows the relations between all study variables. Time pressure was negatively related to all recovery experience variables with the exception of mastery. Role ambiguity and situational constraints were negatively related to psychological detachment and control. Hours of overtime were negatively related to psychological detachment and relaxation but not to mastery or control. Job control was positively related to control during off-job time. Taken together, analysis largely confirmed our hypotheses for job stressors and partially for job control. Correlations between coping and recovery experiences were low and mostly nonsignificant. There were some significant correlations, namely between active coping and the experience of mastery and control. Restraint coping was positively related to psychological detachment and mastery. Seeking instrumental social support showed a positive relation with relaxation and control. Seeking emotional social support was negatively related to psychological detachment and positively related to relaxation and control. Mental disengagement was positively related to relaxation. These generally low correlations between coping and recovery experiences provided partial support for our hypotheses and overall demonstrated that there is only limited overlap between the way an individual responds to a stressors (i.e., coping) and how he or she experiences recovery off the job. Most correlations between the personality variables and the recovery experience constructs were low and nonsignificant indicating that personality seems not to be a core predictor of how individuals experience their off-job time. Openness to experience and extraversion were positively related to mastery. Emotional stability was positively correlated with psychological detachment, mastery, and control. Overall, most of our hypotheses on the relation between personality and recovery experiences were supported. We found moderate relations between recovery experiences and well-being measures. Psychological detachment and control showed negative relations with health complaints, emotional exhaustion, depressive symptoms, need for recovery, and sleep problems. Relaxation showed negative relations with health problems, emotional exhaustion, need for recovery, and sleep problems. Mastery was negatively related to emotional exhaustion, depressive symptoms, and need for recovery. All recovery experience measures showed positive relations with life satisfaction. Except for the burnout dimension disengagement, the overall pattern of correlations supported our hypotheses. Overall Discussion In this article we presented measures for assessing recovery experiences. Confirmatory factor analyses showed that four distinct recovery experiences can be differentiated (psychological detachment, relaxation, mastery, control). The scales have good internal consistencies and are short so that they can be used in future research without putting high time demands on study participants. Correlational analyses showed that job stressors were related to three of the four recovery experiences. The rather high negative correlation between time pressure and psychological detachment is in line with earlier research (Sonnentag & Bayer, 2005) suggesting that time pressure and the associated high workload make it particularly difficult to switch off from work during leisure time. Relaxation was related to aspects of quantitative workload, but not to other job stressors. It might be that particularly prolonged activation because of time pressure and overtime hinders relaxation during off-job time, whereas other job stressors do not necessarily result in prolonged activation but impede other aspects of recovery by depleting self-regulatory resources (Sonnentag & Jelden, 2005). Unexpectedly, job stressors were not related to mastery experiences. It might be that individuals do not react uniformly to job stressors. Some individuals might feel that job stressors hinder them to enjoy mastery, whereas others might deliberately try to counteract the negative effects of job stressors by engaging in activities that provide the opportunity for positive experiences and mastery. Job control was not related to psychological detachment, relaxation, or mastery. One might specu-
